TeO2 (Tellurium Dioxide) is an excellent acousto-optic (AO) crystal with high AO figure of merit, birefringence, good optical rotation and slow propagation velocity along  direction. The resolution of AO devices made of TeO2 crystals will increase several levels than others. It is an ideal crystals for applications of AOM (acousto-optic modulators), AOD (acousto-optic deflectors), AOTF (acousto-optic tunable filters), laser Q-switches and RF spectrum analyzers ect. TeO2 crystals can be used in the field of astronomy, laser publishing, laser recorder and so on.
High figure of merit(M2=793 ×10-18S3/g)
High refractive index (2.2-2.4)
High optical activity (20-500deg./mm)
Acousto-optic modulator (AOM) is applied in production of Q switching in solid-state laser, cavity dumping of solid-state laser, pulse picker ,laser printer and other devices. Acousto-optic deflector（AOD) is applied in production of scanner, laser tweezer, RGB systems for laser projectors, laser scanning microscopy and profilometry. Acousto-optic filter(AOTF) is applied in production of Rapid-scan Spectrometer, Multispectral Imaging, Fiber Optic Communication, Spectropolarimeter and fluorescence spectrometer.
